Application mea April 14,1908. serial No. 427,043.

To all whom it may concern:

Be it known that we, WILLIAM WILLIAM- soN and GEORGE BLUE, citizens of the United States of America, residing at Sharpsburg, in the county of Allegheny and State of Penni have invented new and useful Imof which the following Sylvania,

rovements in Sieves, isa s eciiication.

This invention relates to culinary sieves, and one of the principal objects of the same is to provide a sieve in which the screens and the agitators may be entirely removed from the casing for cleaning.

Another obj t of the invention is to provide asieve in which the hinged bottom may be readily opened by means of a spring handle to discharge the sifted contents of the casing.

.These land the accompanying drawing,'in which,-

the casing.

Referring to the drawing for a more specific description of the invention, the numeral 1 designates the casing which, as

Y shown, is a hollow cylindrical device. EX-

tending across the bottom of the casing is a cross bar 2, said bar being headed up, as at 3, to the casing and provided in its center with a attened portion 4 having a conical socket 5 therein to receive the pointed lower end 6 of the vertical shaft 7 provided with a hand crank 8 at its upper end and an operating handle 9 connected to said crank. The shaft 7 is supported near its upper end by means of a cross bar 10 which is bent around lthe shaft 7 lto form a bearing 11, the ends of said bar 10 being provided with buttons or disks 11 and said cross bar being detachably connected to the casing by means of the bayonet slots 12, as will vbe understood'. As shown, there arejfour screensl, 14,- designed to be of different degrees of finethe screens 13 being secured together by means of the wires 15 which extend down and around the binding wires 16 at the outer ness,

other objects may be attained by means of the construction illustrated .in

edges of saidscreens upon opposite sides thereof. When it is'desired to remove the screens from the 'casing foi; the purpose of cleaning the. same, the cross bar l() isl moved to one `side vto vpermit the same to pass out of the -bayonet slots 12 at the upper edge of the casing. By then withdrawing the shaft 7 all of the screens are removed with it.

Agitators, consisting 'of wire loops 17, are mounted upon theshaft 7 by means of ends of theagitators 17. These-agitators strandsA 19 adapted to pass over the tops of the screens in .close-connection therewith to agitato-.the flour or rother material being sifted and pass it quickly .through the sieves. Whenever required, the shaft 7, the cross bar 10 and the sieve 13 are removable from the casing 7 to permit the same to be readily cleaned;

The bottom 20 of the sieve is connected to the casing 1 by a hinge 21, and s aid bottom is heldclosed byy means of a spring support comprising a shank 22 secured-in a keeper 23 in the handle 24. The shank 2 2 extends upwardly and is formed into a coil 25 from whence the wire strand is .bent downwardly, as at'26, and a wooden'handle 27 islaced thereon. The strand 26 exand is bent at right angles, as at 28, and is provided with a terminal loop 29. When it is desired to discharge the contents of the sieve the wooden handle 27 is grasped and moved to the dotted line position, when the bottom 20 ofthe sieve wil drop to the position-shownl in dotted lines inl Fig. 1, thus permitting the sifted material to be discharged.

The invention is of simple construction, is easy to clean, will operate quickly and -can be manufactured at slight cost.

Having thus described the invention, what is claimed as new, isz-- `,The herein described sieve comprising a casing,` a series Vof screens therein, a shaft extending through the screens, a series of agitators secured to said shaft and bearing upon the upper surface of said screens, means whereby said screens, shafts may be disconnected from the casing suitable hubs 18 in which are secured the are provided with plain horizontal bottom tends t rough the bottom of the handle 24 Y 1.0.5 agitators and l a handle conected to the casing adjacent In testimony whereof We alix. our signato the hinge, and a spring sup orte' for tures h1 presence of two Witnesses.` normally holding said bottom o osed, said fWILLIAM WILLIAMSON. supporter comprlsng' a s' ring having one GEORGE BLUE.
